During his ownership of FC Sion, Constantin has made upwards of 50 managerial changes and appointed himself as manager in 2008 and 2021. He once fired a head coach because of his scent and allegedly assaulted Swiss league referee Markus von Känel in 2004 during a live match broadcast. In 2017, he kicked Austrian pundit and former coach Rolf Fringer down to the ground on live television during a Swiss league match for which he received a 14-month ban. In 2023, he fired Sion's then-manager David Bettoni at half-time during a match against Servette before forcing him to stand on the side lines for the remainder of the game. In a separate episode, he verbally confronted Mario Balotelli (whom he had signed). In 2011, Constantin signed six players under a transfer ban because of what happened with Essam El-Hadary’s transfer, and appeared on live TV on a horse.

Yet under his presidency, the club also experienced considerable success, such as winning the Swiss Cup in 2006, 2009, 2011 and 2015. Constantin was formerly a goalkeeper who played for Neuchâtel Xamax (1977–1979), FC Lugano (1979–1980), FC Monthey (1981–1982) and FC Martigny-Sports (1983–1984). In March 2020, Constantin sacked 9 of his FC Sion first-team players after they refused to take a pay cut after the outbreak of the COVID-19 and suspension of the Swiss Super League. In 2014, Constantin appointed his son Barthélémy as Sporting Director of FC Sion, a position he has held ever since.

Christian Constantin is recorded as architect, merchant, association football player and association football coach.
